ADJUSTABLE AND EXTENSIBLE BRACKET.

Specification of Letters Patent.

Patented Jan. 21, 1908.

Application filed eptember 12. 1907. Serial No. 392.546-

To all whom it may concern:

Be it known that I, LYMAN J. RHoADEs, a c1t1zenofthe UnitedStates,.residing at Fond.

tools, etc. it may; be used in a cases where 4 use of such a bracketwould prove desirable and advantageous.

The object of my invention is the production of a simple, economical,ornamental and novel bracket that may be extended or adjusted to answerall purposes requiredof a device of thischaracter.

A further object of he invention is to embody in a bracket means wherebyit may be securely locked in position after being properl adjusted.

ith these objects inview the invention consists of certain novelfeatures of construction, combination and arrangement of parts as willbe more fully described and articularly pointed out in the a pended caims.

In the accompanying rawin'gs, Figure 1 is a view in side elevatibn of abracket 'constructed in accordance with my invention; Fig. 2 is a viewof a bracket constructed in accordance with my invention, looking at the:opposite side of the bracket; and Fig. '3 is a detail means rspectiveview of aform of locking employ to lock said bracket inposition afterbeing, properly adjusted.

Referring .how'more particularly to the drawings, the numeral 1represents a vertical supporting bar, which is hinged to one face of aplate or block, 2, of preferably rectangularform, adapted to be screwedor otherwise securely-fastened to the wall or a suitable object. Thenumeral 3 reresents two parallel bars, which are pivota y connected neartheir innere'nds to. the ends of said vertical 1 supportingb'ar '1, andare connected at their outer or op osite ends. by a connecting hnk orbar, 4;. o retainsaid parallel bars 2 at the proper adjustment, I employa diagonal brace bar, 5, which is pivoted at or near its inner end nearthe inner end of the ower arallel bar, as at 6, and 1s adapted to beocked at its opposite or outer end to the upper parallel bar by alocking device comprising a sliding clip, 7, slidably engaging andextending somewhat over the upper edge of the bar, and a cam lever, 8,eccentrically pivoted to said sliding clip as at '9, and alsoeccentrically pivoted to the outergend of said diagonal brace bar, 5.The numeral 10 represents lazy-tongs, which are hingedly connected attheir innerends to said connecting link or bar, 4, ,and have hingedlyconnecte to their outer ends a horizontal supporting member, 12,comprising a horizontal arm, 13, and an oblique brace arm, 14, arrangedbelow said horizontal arm and-serving to brace the same.

It will be seen that by adjusting said parallel bars 3 at a. suitableangle with" respect to a vertical plane, said horizontal-s11 portingmember 12 may be raisedor lowered to suit all requirements. It. willalso be seen that by employing lazy-tongsbetween said connecting link"or bar- 4 and said horizontal supporting member 12, said supportingmember may be extended at a greater-or less distance from the wall orthe object to which'my improved bracket is secured. Either orboth ofsaidlazy-tohgs and horizontal supporting- 10 and 12, respectively, maybe.

member, swung in a horizontal plane to secure the desiredrelativeposition of the tool or other object carried by said sup ortingmember.

A particularfeature o my invention resides in my im rbved meansforautomatic ally locking sai parallel bars in position after theyhavebeenproperly adjusted, as the greater the strain or Weight exerted on orcarried by saidhorizontal sup, orting member, the greater the. force witwhich said sliding clipfand the oat of said cam lever, clamp oppositesides of the .upper arallel blar, thusfobviatin f b I si pin 'romosltion'a ter ein 'ro er ad uste d.v To djustsaidparalle o arsi at ii sutable angle with respect to a vertical plane, andt ere'by raise 'orlower said horizontal sup orting member, as the case may be, it is o 'ynecessary to raise the free end of said camlever to release the camthereof and said slidin clip from engagement with the op, osite e ges ofthe upper parallel bar.

aving described my mvention, I claim:

1. In a bracket, the combination, of two parallel bars, a'brace barpivoted to the all liability of the racket lower bar, a sliding clip onthe u or bar, a lever eccentrioally pivoted to s'aicPErace bar, andhavin a cam at its pivoted end eccentricall plvoted to said clilazy-tongs hinge.

horizontally, and a horizontal sup orting member hinged to the free endof sai lazy-tongs, substantially. as described.

2. Ina bracket, the combination, of two arallel bars, a brace bar ivotedto' the ower bar, a sliding clip on t eu er bar,'-a

lever eocentrically pivoted to sai brace bar and having a demo at itspivoted end 'eccentricall pivoted to said. clip,v and lazy-tongs hingeto adjacent ends, of said parallel bars and arran ed horizontally. i

g 3. In a racket, the combination, of a supporting plate, two parallelbars hinged to said late and adapted to swing in a horizontal p ane, adiagonal brace bar pivoted to the lower parallel bar, a sliding clip onsaid upper parallel'bar, a lever eocentrioally pivoted to said'brace barand having a cam at its pivoted end eooentrically pivoted to saidslidingclip. v

to adgacent ends of sai parallel bars and arrange 4:. In a bracket, thecombination, of a supporting plate, two parallel bars hinged to saidplate and adapted to swing in a horizontal plane, a diagonal brace barpivoted to the lower parallel bar, a sliding clip on said upperparallel-bar, a lever eccentric'ally pivoted to said brace bar andhaving a cam at its pivoted end ecoentrically pivoted to said slidingclip, lazy-tongs hinged to the free ends of said parallel bars and ahorizontal support hinged to the outer end of said lazy-tongs.

5. In a braoket the combination, of two parallel bars, a diagonal bracebar pivoted to the lower parallel bar, a clip on said upper parallelbar, and a cam lever eccentrically pivoted to said clip'and brac-e'barand adapted to co-act therewith in looking said parallel bar s'in anadjusted position.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses. I i LYMAN J. RHOADES.
